Chapter 5: Fileshare and CCI

A number of components of Mainframe Express use the Micro Focus components Fileshare for handling files over a network and CCI for handling communications. You do not need to change your programs to use Fileshare or CCI in your mainframe applications. However, you need to understand how to set up Fileshare and CCI to enable the relevant components to work correctly.

In Mainframe Express you are not licensed to use Fileshare or CCI in your applications. If you want to write applications using either of these, you must have Micro Focus Net Express (for developing distributed applications). Please contact your Micro Focus sales representative for full details of Net Express.

The components that use Fileshare and/or CCI are:

Mainframe Access uses CCI for:
- Mainframe Access Drag and Drop facility to download and upload files between the mainframe and PC
- SourceConnect to enable you to access source files on the mainframe directly using Mainframe Express file-processing tools such as the Compiler, Assembler and debugger
- DataConnect to enable you to access data files on the mainframe directly using COBOL applications running on the PC
CICS Option uses:
- Fileshare to provide VSAM data integrity - enables the use of CICS forward and backward recovery
- CCI to provide:
  - Support for peer-to-peer CICS communications between CICS Options
  - Thin client support such as remote ECI requesters and remote 3270 terminals
IMS Option uses Fileshare to provide:
- Shared update databases (sharing with other users and updating them)
- Commit and rollback support for Checkpoint/Restart testing
Fileshare itself also uses CCI to provide the network communications

The documentation for each component explains how Fileshare and CCI are used and helps you with setting them up. However, we also supply the Fileshare User Guide and Configuring CCI for more information.

The Fileshare User Guide explains how Fileshare works and how to configure it. It also explains how to use Fileshare from your own applications. This is not relevant to mainframe applications. (If you want to create PC applications that use Fileshare, please ask your Micro Focus sales representative for details of Net Express.)

CCI can communicate over a number of different protocols. Configuring CCI helps you select the protocol to use and to configure CCI.
